1.15.2 Mod making: code not working for ModItemGroups

[llamacorn1921]

so im following this tutorial [https://cadiboo.github.io/tutorials/1.15.2/forge/1.7-itemgroup/] and I'm completely new to all of this. I'm literally copy and pasting while adding stuff so some lines are colored and styled like the site says but noting is working. This is what the log says:  

error: invalid method declaration; return type required
        public ModItemGroup(final String name, final Supplier<ItemStack> iconSupplier) {
               ^
1 error

this is the code

package com.[REDACTED].[REDACTED].init;


import java.util.function.Supplier;

import com.[REDACTED].[REDACTED].[REDACTED];
import net.minecraft.item.ItemGroup;
import net.minecraft.item.Items;

[File: ModItemGroups.java]


public static class ModItemGroup extends ItemGroup {

	private final Supplier<ItemStack> iconSupplier;
	public ModItemGroup(final String name, final Supplier<ItemStack> iconSupplier) {
		super(name);
		this.iconSupplier = iconSupplier;
	}
	@Override
	public ItemStack createIcon() {
		return iconSupplier.get();
	}
	public static final ItemGroup MOD_ITEM_GROUP = new ModItemGroup([REDACTED].MODID, () -> new ItemStack(ModItems.EXAMPLE_ITEM));
}

[File: ModItems.java]

package com.[REDACTED].[REDACTED].init;

import com.[REDACTED].[REDACTED].[REDACTED]; //Main File for the ModName.MODID so its colored and styled
import net.minecraftforge.registries.ObjectHolder;

@ObjectHolder([REDACTED].MODID)
public class ModItems {
	public static final Item EXAMPLE_ITEM = null;
}

[FIle: MOdEventSubscriber.java]

package com.[REDACTED].[REDACTED];

import com.[REDACTED].[REDACTED].init.ModItemGroup; // for stuff to be colored and styled

import net.minecraft.item.Items;//part of this i took from another post from the same problem I had eariler since I know nothing for inports and just barley started to understand gradle errors
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.event.RegistryEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.registries.IForgeRegistry;
import net.minecraftforge.registries.IForgeRegistryEntry;

@Mod.EventBusSubscriber(modid = [REDACTED].MODID, bus = Mod.EventBusSubscriber.Bus.MOD)
public final class ModEventSubscriber {

	@SubscribeEvent
	public static void onRegisterItems(RegistryEvent.Register<Item> event) {
		
		event.getRegistry().registerAll(
				setup(new Item(new Item.Properties().group(ModItemGroup.MOD_ITEM_GROUP)), "mega_cookie")
		);
	}

	public static <T extends IForgeRegistryEntry<T>> T setup(final T entry, final String name) {
        return setup(entry, new ResourceLocation([REDACTED].MODID, name));
	}
	public static <T extends IForgeRegistryEntry<T>> T setup(final T entry, final ResourceLocation registryName) {
        entry.setRegistryName(registryName);
        return entry;
    }


}

if anyone knows what the problem is or could give hints or something then please tell me

email is: [email protected]  [yea i know. made it when i was like 14 or something so about 4 years ago]

ok, i removed 'class' from "public static class ModItemGroup extends ItemGroup {" and now the "error:  invalid method declaration; return type required" doesn't show with "public static final ItemGroup MOD_ITEM_GROUP = new ModItemGroup(ExampleMod.MODID, () -> new ItemStack(Items.LIGHT_BLUE_BANNER));" being underlined but now im getting

Why does your static class have a constructor?

[llamacorn1921]

so......i forgot the maker of the tutorial had a github so i looked through it....my problem was that "public static final ItemGroup MOD_ITEM_GROUP = new ModItemGroup([REDACTED].MODID, () -> new ItemStack(ModItems.EXAMPLE_ITEM));" needed to be at the top and not at the bottom.  i. atleast i know how to read gradle logs now. sorry for the trouble
